Thursday to Saturday will have another dangerous winter situation in the southern U.S. Here's a timeline on where and when you have to be at a certain location to avoid the danger.

Cities that are not accustomed to seeing much snow or ice, like Dallas, could experience significant accumulations.

At least some areas of light snow, sleet and freezing rain or drizzle may develop in the Southern Plains Wednesday night. Parts of northern Texas, Oklahoma, Arkansas, southern Kansas and southwestern Missouri are forecast to see snow. A band of sleet and freezing rain may stretch from central Texas into northern Louisiana and southern Arkansas.
